To all whom t may concem':

Beit known that I, GEORGE'W. NIBBE, a citizen of the United States, residing at Chicago, in the county of Ceok and State of Illinois, have invented certain new and use ful Improvements in a Tie-Plate, of which the following is a specification. My invention relates to tie platesand has particular reference to a tie plate having diagonally extending non-cutting tie engagandv having recesses formed in the body of the tie plate between the diagonally 'extending ribs which serve as cushions'under-the tie and lighten the plate without objectionably lessening its strength. 'I he diagonally extending ribs become embedded into the tie across the grain thereof, when the tie plate is in po-v sition upon the tie andunder the rail base, 'so that splitting of the tie recesses on the underside of said tie plate also assisting in preserving of its cushioning resistance tothe embedment of the tie plate.

Another lobject of my invention is the plate. having longitudinallyv extending marginal ribs on its underside so that moisture, is prevented from entering underneath the tieplate and thereby rotting the ties andthe tieplate isnenabled to grip the tie V to a better advantage, and also having a centrally located longitudinally extending rib to whichthe diagonallyj extending ribs are joined .which serves to strengthen thetie plate. n

Another object of my invention isthe provision of a tie plate having the structural features above set forth in combination with a cambered or curved top' which causes the tie plate to better perform its function and enables the tie plate to'become firmly' seated upon the tie and serve asa part thereof, that is,`the'tie plateand tie do not move relative to each other, this movement, if any, being between the rail and the tie plate. This form also prevents the tie plate from rattling and having its sides rocked back and forth by the movement of trainsl which causes the tie plate to cut intothe tie and destroys the bers of the tie plate which happens when the rail bearing surface of the` tie plate is flush withthe rall. i

1Anotherobject of my 'invention is the provision of tural features heretofore set forth with respect to the bottom thereof and in addition thereto having nthe usual rail abutting shoulenable the weight is avoided, the

the tie because i a tie plate having the strnc.

der extending transversely across the top thereof with a sloping or canted cambered surface extending downward from the side of the tie plate upon which the shoulder is located to a point approximately even with the inside edge of the rail base, so thattherail is 'tilted slightly in order'to accord a better resistance to the'weight and thrust of the car wheels upon the rail and tobetter of the car to be transmitted en to the tie Another and further object of my inventionis the provision of a tie plate which is simple in construction and which is stronger than any other tie plate 'of equal weight, therefore having greater resistance to buckling and affording greater resistance Ato track spreading vbecause of the diagonal ribs.

These and other will be more fully reference to th and in which-' Figure l is a side elevational view of my improved tie plate showing the cantedcambered top; Fig. 2 is a bottom proved tie plate; and

Fig. 3 is an end view in elevation of my improved tie plate showing the canted cambered top surface.

"Referring now specifically Ito the. drawings, and.y in which like reference characters refer to like vparts throughout, 10 is a tie Aplate body having the usual rail abutting transversely extendin shoulder 11 on the upper side thereof. s indicated at 12, the top surface of the tie plate body 1 0 upon which the rail base is seated 1s slightly curved or'cambered, the high portion 13 beand better understood by accompanying drawings,

plan view of my .im-

xingin the middle of the said plate and curvbody 10 and from this point to theedges thereof the tie plate slopes downward at a slightly greater degree, thus lengthening the tie plate without impairing its efficiency.

/ Referring now specifically to Fig. 2, which l illustrates the underside of the tie plate body 1 0, I provide a pair of longitudinally ex,- tendingmarginal ribs 16 and 17 and a centrally located longitudinallyfextending rib 18. Extending diagonally across the said plate in a straight line.

objects of my invention tie plate body- 10 and joined to the marginal rib 16 at one end and to the rib 18.at their other ends are a plurality of diagonally extending spaced tie engaging ribs 19, the said ribs being on one side of the bottom ofthe tie plate body, other ribs 2O joined to the marginal rib 1T and to the central rib 18, the said ribs 20 joining the rib 18 -at points opposite the ends of the ribs 19 where they join the central rib 18. Between the ribs 19, the marginal rib 16 and the central rib 18 are a plurality of recesses 21 extending into the tie plate body 10', these recesses being arcuate in cross-sectional shape and therefore deepest `at their central portions. The recesses 21 extend parallel with the ribs 19 and have their side edges spaced from the.

ribs 19 a short distance and theirl ends spaced apart from the said ribs 16 and 18. Similar' recesses 22 are provided between the diagonally extending ribs 20, the marginal rib 17 and the central rib 18 on the opposite side of the tie plate bottom.

The recesses serve as cushions and in conjunction with the spaces between them and the ribs prevent excessive einbedment of the tie plate into the tie. A

The construction of the recesses parallel with the ribs 19 and with the added strength ofthe ribs and the spaces between the recesses and the ribs, prevents the tendency tobuckle, which is ordinarily found in the tie plates with corrugated tops or bottoms. By adding about half of the metal saved by the recesses, to the rail bearing surface and behind the shoulder 11, the tie plate is given enough additional strength to make it much stronger than any other plate of equal weight.

It will bek noticed that the ribs 19 and 20` the. underside ofl extend diagonally across the tie plate so that the thrust outward of the tie plate tends to compress the fibers of the tie on the top surface thereof so that better resistance is afforded the tie plate than if the said ribs extended in a straight line transversely across said tie plate.

The tie plate by reason of 4its construction is rolled b v what is commonly called the end over end. method, therefore permitting a true and centrally located camber to be rolled on it and also producing a tie plate of added service by reason of the rail action being against the grain of the steel.

vhile I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the roportion of parts and the substitution o equivalents as circumstances lmay suggest or render expedient without departing from the spirit or scope of my invention.

I claim:

.1. A tie plate having an upper rail receiving surface and a rail abutting flange of said plate,

inner ends to the said central rib and to the i marginal ribs at their outer'ends and having a series of recesses in the body of said tie plate between said diagonally extending ribs respectively and between the central rib and the marginal ribs.

2. A tie plate having an upper rail receiving surface and a rail abutting flange extending transversely thereof, the said rail bearing'surface being lcambered transversely and a bottom tie engaging surface having longitudinally' extending ribs on its marginal edges, and a longitudinally extending central rib intermediate its edges and a series of diagonally extending tie engaging ribs joined at their inner ends to the said central rib and to the marginal ribs at their outer ends and having a series of recesses in the body of said tie. plate between said `diagonally extending ribs respectively` and between the central rib and the marginal ribs.

.3. A tie plate having an upper rail receiving surface and a rail abutting flange extending transversely thereof, the said rail bearing surface being canted longitudinally of. said plate and cambered transversely thereof, and a bottom tie engaging surface having longitudinally extending ribs on its marginal edges, and a longitudinally extending central rib intermediate its edges and a series of diagonally extending tie engaging ribs joined at their inner ends to the said central rib and t'o the marginal ribs at their outer ends and having a series of recesses in the body of said tie plate between said diagonally extending ribs respectively and between the central rib and the marginal ribs.

4. A tie plate having an upper rail receiving surface and a rail abutting flange extending transversely of said plate and a bottom tie engaging/surface having longitudinally extending ribs on its marginal edges, a longitudinally extending central rib and a series of diagonally extending tie engaging ribs joined at their inner ends to the central rib and to the marginal ribs at their outer ends, the said tie. plate having a series of arcuate shaped recesses extending parallel with said diagonally extending tie said recesses having their engaging ribs, f th d.
